Answer 1

Пошаговое объяснение:

$1) - 5 \times (4.7 - 4.9) = - 5 \times ( - 0.2) = 1$

$2)( - 0.4 - 0.8) \times 1.5 = - 1.2 \times 1.5 = - 1.8$

$3)(2.7 - 2.9) \times ( - 4.5) - 3.02 = - 0.2 \times ( - 4.5) - 3.02 = 0.9 - 3.02 = - 2.12$

$4) - 2.8 \times 5 - 4 \times ( - 0.7) = - 14 - 4 \times ( - 0.7) = - 14 - ( - 2.8) = - 14 + 2.8 = - 11.2$

Answer 2

Відповідь:

Покрокове пояснення:

1.-5(4.7-4.9)=-5*(-0.2)=1

2.(-0.4-0.8)*1.5=-1.2*1.5=-1.8

3.(2.7-2.9)*(-4.5)-3.02=-0.2*(-45)-3.02=0.9-3.02=-2.12

4.-2.8*5-4*(-0.7)=-2.8*5-4*(-0.7)=-14=2.8=-11.2
